Specification or Lettsrs Patent.

Patented Oct. as, 1907.

Application filed July 12; 1904- Serial No. 216335.

My invention relates tozmachines for measuring and weighing cereals and their ground products, and is designed particularly for use in connection with a flour packer where it is desirable to deliver to the packing anger the desired amount to fill a sack marked for a certain weight.

The object of the invention is to provide a machine wherein the mea uring and weighing operation is quickly and accurately performed, thereby insuring large capacity and great efliciency for the machine.

A further object is to provide a machine which can be easily and quickly adapted for filling sacks of different size.

Other objects of the invention will appear from the follouing detailed description.

The invention consists generally inrnechanism for measuring the flour or other material preparatory to the packing operation. g

Further the invention consists-in providinga measuring device capable of expansion and contraction, according to the size of the sack to be filled.

Further the invention consists in providing a secondary feeding mechanism in connection with the measuring device.

Further the invention consists in an improved scale hopper and mechanism for discharging its contents.

Further the invention consists ,in various constructions and combination, all as hereinafter described and particularly pointed out in the claims.

In theaccompanying drawings, forming a partof this specification, Figure 1 is a rear elevation of a weighing and measuring machine embodying my ip. vention. Fig. 2 is a side elevation of the same. Fig. 3 is a vertical section on the line qs-a of Fig. '1. Fig.

of Fig. 5. Fig. 7is a similar view on theline y y. of Fig. 5. Fig. 8 is a horizontal sectional "view on the.

line 2-2 of Fig. 5. Fig; 9 is a vertical sectional view} I section on the line a a' of Fig. 5. 13 is a vertical section on the line 29-23 of Fig. 3, the being shown in its'raised position. Fig. 14 is is vertical section on the line :c'-a: of Fig. 13. Figs. 15 and 1'6'are details of a portion of the mechanism use'd'for opening one hopper and closing the other. Fig. 17 is a detail sectional view on the line y y" of Fig. 13.

In the drawing (see Fig. 5), 2 represents a suitable frame wherein the measuring and weighing mechanism is supported. 3 is a horizontal shaft mounted in bear.- ings in said frame and having a driven pulley 4 at one end and a sprocket 5 at the other. Bevel pinions 6 and 6' and 7 are mounted on said shaft and adapted to engage bevel gears 8 8' and 9 that are keyed on the shafts 10, 10 and 11. The shaft 3 is operated continuously is a'flour spout 12 having branch spouts at itslower end. These branch spouts have similar functions and are each equipped with a measuring mechanism beneath which weighing hoppers are provided.

The measuring and weighing mechanism in onefrom some suitable source of power Near the shaft 3 I spout is practically a duplicate of the one in the other vices, while similar in construction and operation, are

oppositely arranged, that is, one will be open to dis: charge its contents while the other is being filled, and a corresponding condition will exist between the scale hoppers beneath, being filled and emptied alternately. This arrangement allows the continuous operation of the machine and largely. increases its capacity.

In the drawing I have designated one of the branch spouts by reference numeral 12 and the other by a similar reference numeral with theadditibn of the exponent a, as above stated.

A cup 13 is splined on the lower end of the shaft10 and adapted to receive the tapered head 14 of a vertically arranged shaft 15. A sleeve 16 is loosely mounted on said shaft and a ring 17 is splined on the upper end of sleeve andis threaded to receive the lower end of the cup 13. Movement of the ring 17 up and down on its sleeve'will raise the cup 13 away from the tapered head 14' or allow it to contact therewith. The sleeve 16 moves continuously through its connection with the shaft 3, while the shaft 15 has an intermittent movement, depending on the position of the clutch members A bell 18 is pivotallysupported between the spouts and has a forked arm 19 pivotally con-' nected withthe ring 17, and 9. depending arm 20 through-which the bell crank-is rocked.to'throw the clutch mechanism into its operative or inoperative sition. Below the branch spout 12 I provide a cylindrical receptacle 21 wherein the measuring-operation is performed. The bottom of this receptacle rests upon a plate 22 having triangular discharge' openings 23 through which the flour or other mateiial'that is being measured is delivered to the scale hopper beneeth' (see 5 to 9). 7 Above the plate 22" and secured on the. lower end of the shaft 15 is'a se'ctor-shaped-plate 24 adapted to'coincide and close the op'eningsj23. inthe plate 22 beneath. A plate 25 is loosely mounted on the sleeve 16 and has openings, corresponding to those in the plate 22, and a stationary plate forming the top of the receptacle, while the plate 22 constitutes the bottom thereof. A plate 26, also sector-shaped, is loosely mounted below the plate 25 and adapted to close the openings therein and check the feed of material into the measuring receptacle. Straps 27 securedto the plate 26 l-av'e a sliding connection with arms 28 on the plate 24, said connection allowing the vertical adjustment of the plates and 26, to vary the size of themea'sure and also serve to transmit the revolving movement ofthe plate 24 to the plate 26. As above stated, these plates are similar in form but are oppositely arranged, one closing the openings in its plate while the other uncovers corresponding openings in the other plate and it, therefore, happens that when the feed openings in the measure are uncovered, the discl. arge bpenings will be closed and vice versa.

I The plate 24 is provided at its upper surface with rat-- ,Gial ribs 29 having slots 30 (see Figs. 7 and 9) through which curved tooth ed arms 31 are arranged to operate. These arms are mounted on the lower end of the sleeve 16 and turn continuodsly therewith. Their function i is to feed the flour or other material out 'of thelittle pockets-32 formed by the ribs 29 on the surface of the would not be necessary to provide any weighing apparatus in connection with a packer, as a measure could be easily constructed that would hold the proper.

' amount of flour for the sacks of different size. It has been found, however, that fiour, as well as other cereal products, varies considerably in weight tixzough t1; e bulk may be the same and it is, therefore, necessary to weigh the flour either before or after its delivery to the sack.

I have found that by employing the measuring device in connection with the scale that all the flour necessary to fill a sack, except a little to balance the scale, can be dumped into the scale hopper at one operation instead of being slowly fed thereto, and the capacity of themachine is thereby greatly increased.

To adjust the upper plate or top of the measure in diffcrent positions, according to the size of the sack to be fiiled, I provide a shaft 33 (see Fig. 6) ldaving arms 34 s cured thereon that are pivotally connected by links 36 (see Fig. 9) with the plate 25.

Acrank 37 (see Figs. 1, 2 and 6) is secured on tlze shaft 33 and is provided with a pin 37 adapted to fit holes in blocks 38 adjustably mounted on a curved bar" 39 having marks (not shown) to indicate the proper position of the crank for sacks of different size. An adjustable stop '40 is arranged on the bar 39 by means of which movement of the crank may be limited.

Suitable stirring arms 41 are mounted'on the sleeve 16 within the measuring receptacle, and a third arm 42 for a purpose is provided on the top of the measwe and servesto prevent flour or other material from clogging in th e opening leading thereto.

Below the spouts 12 and 12" i's acone shaped casing 43 within which the scale hoppers arearranged. These hopperscomprise open topped receptacles 44 and 44" secured together by brackets 45,-an'd provided with pivoted doors 4'6 and 46 arranged to close the bottoms of the hoppers. A yoke, 47 has knife edge bearings 48 in brackets 49, on each side of the machine at the rear, and scale levers 50 have bearings 51 on said brackets at one end and links 52 connecting their other ends with the yokes 47 (see Figs. 4, 5-and12). Links 53 and 54 connect the scale lever 50 and the yoke 47 with arms 55 provided Tm brackets 56secured to the'sides of the scale hoppers andprojecting through the walls of the cone shaped casing 43;v

. A scale beam 57 is, secured to the yoke 47 (see Figs.

3, 4, 12 and 14) and is provided with the usual balance weights, one of which is adjustable on the beam to allow the scale hoppers to be brought to a balance. The

closing and opening the scale hoppers and for regulating the discharge of flour from the measuring receptacles. Between the scale hoppers I provide hangers 58 wherein ashort shaft 59 is journaled. A sleeye 60 is keyed on this shaft and provided with an arm 61 having a forked outer end having pivotal connections 62 with the hinge bottoms 46 and 46" of the scale hoppers. Turn-buckles 63 are provided in said pivotal connections to allow the proper adjustment of the hinged bottoms (see Figs. 5 and 14).

A block 64 is mounted on the forward end of the shaft 59 (see Figs. 14, 15 and 16) and provided with a centrally arranged lug 65 on its outer face that extends between lugs 66 on a plate 67. This plate is arranged on the wall of the cone shaped casing 43 and is held in place by pins 68 that pass through said plate and through a slot 69 in said wall, and also through slots 70 in a block 71 on the outer surface oi said wall and finally are secured in a plate 7.2 that is arranged to slide horizontally on said block 71. The slot 69 allows the vertical movement of the block 71 while the plates 67 and 72 move vertically with said block and have in addition a horizontal movement in the slots 70 independently of said block. The block'64 is provided on each side, at both ends, with lugs 73 and 74; the former are on the inner side and engage the hangers 58 to limit the movement of the block, while the lugs 74 are in the path of the plate 67. to cause the oscillation of the block 64 and its shaft when the plate is depressed.

A rod 75 vertically movable in bearings in a bracket 76 is secured at its upper end to the block 71 between the slots therein. A sleeve 77 is secured on said rod and below said sleeve is a loose washer 78. A spring 79 is coiled about said rod between the brackets 76 and said washer, and lugs 80 providedou said bracket in the path of the washer prevent the spring from exerting its power on the rod beyond a certainpoint, but allow the rod to be moved vertically wllen'desired.

ssasss The principal function of the spring 79 is to return the rod to its normal position after each operation of the machine (see Figs. 13 and 14). Above the plate 72 (see Figs. 13 and 14) are two vertically movable shafts 81 and 81 slidable in guides 82 on the machine casing and normally held in a. depressed position by springs 83 arranged between the guides 822ml blocks 84 adjustable on said shafts. The upper ends of these shafts are provided with levers 85 and 85 (see Figs. 7, 13 and 14). These levers are identical in construction and operation and a description of one will suffice. it being understood that the other is similarly arranged and operates in substantially the same manner. The end of the lever 85 projects through a slot 86 in the casing 43 between stops 87 on a ring 88 arranged at the top of the conical casing (see Figs. 7 and 13). Sufficient space is provided between the stops 87 to allow horizontal movement of the lever. and the slot 86 is of sufiicient size to permit such movement and also a vertical movement. An arm 89 is secured on said lever and arranged to engage the arm 20 of the contiguous bell crank. said arm being normally drawn toward the corresponding arm of the other bell crank by a spring 90. the effect of such drawing movement being to set the clutch mechanism, and start: the shafts 15 which control the feed and cut-off devices of the measuring receptacles. The plate24, which I prefer to designate as thecutoff plate. is provided with four 7 stops 91 and 92 oppositely arranged and in different horizontal planes, the stops 91 being above the level of the other two. The end of the lever projects in the path of these stops and in its depressed position engages one of the stops 92 and arrests movement of the cutoff. and in its elevated position engages one of the other stops 91, for a similar purpose. There being four of these stops. two upon each side of the cut-off. it follows that the revolving plate or cut-off device will have an intermittent movement. making four stops with each revolution. each movement being equal to a quarter turn. and the discharge and openings in the bottom of the machine will in consequence be alternately exposed and covered by the movement of the cut-off plate.

As soon as the lever 85 has been moved to clear the stop with which it is in contact, the tension of the spring will swing the lever 85 to one side of the slot 86 and oscillate the bell crank to set the clutch and start the shaft on that side of the machine. The cut-off will make a quarter turn, when one of the other steps will en-- gage the lever 85, return it to the other side of the slot 86, separate the bell cranks andrelease the clutch to stop the shaft and cut-off.

The scale beam 57 extends between the shafts 81 and 81" (see Figs. '1 and 13) and is adapted to trip the bell cranks 93 ,which have one arm extending 'over the scale beam and the other arm arranged to enter a notch 94 in blocks 95 secured on'the shafts 81 and 81. When one of the shafts is raised the bell crankwill drop by grav-v ity into the notch in the block and prevent downward movement of the shaft until the bell crank is tripped by the tilting of the scale bottom when the hopper is filled.

The shaft 11 is continuously driven from the shaft' 3' through the gears 7 and 9 and the lower endof said shaft 11 is concentric with the cylindrical lower end of the casing 43 and provided with angers 99 (see Fig. 14). A frame 100 is provided on each side with anti-friction rollers 101 adapted to travel between rods 102 vertically withoutany attention on the part of the operator.

arranged in the machine frame. A bracket 103 is provided on the frame 100, having a slotted floor 104 whereon the sack 105 rests while being filled. The sack will telescope with the lower end of the packing cylinder, as shown 11 Fig. 14, and-will gradually be depressed as it is filled.

I will now describe the mechanism for raising the sack platform and simultaneously starting the measuring and weighing mechanism to supply a quantity of flour, or other material, to the packing auger. 106 is a continuously driven shaft mounted in the lower portion of the machine frame and provided with a sprocket wheel 107 driven by a chain 108 from the sprocket 5 on the shaft 3 (see Figs. 1, 5 and 13). Acompensating gear is mounted on the shaft 106 and comprises a member 109 splined on the shaft and having teeth to engage thepinions 110. on the loosely mounted middle member or ring 111. The other member 112 of the gear engages the pinions on the other-side and is provided with holes 113 arranged to register with similar holes in a brake wheel 114 integral with the gear 112. A pinion 115 is loosely mounted on the shaft 106' and is provided with a flange 116 carrying pins 117 that are slidable in the holes 113 and are adapted to engage lugs 118 on the wheel or ring 111. When, therefore, these pins are moved into the path of the lugs 118 the pinion, the wheels and the compensating gear will all be temporarily locked oathe'shaft through their connection with the splined gear.member 109.

A rack bar 119 is mounted on the frame 100 with its teeth in engagement with the pinion 115 and the revolution of the pinions will cause a vertical movement of the rack bar and the frame 100 (see Fig. 13).

The wheels 111 and 114 are provided with brake straps 114 that are pivoted at one end and provided at their other ends with coil springs 114 connected to adjusting threaded pins 115. By means of these pins the relative frictional contact of the straps with the rims of the wheels can be adjusted to regulate the speed of descent of the frame or carriage 100 and thereby regulate the packing of the flour. If the carriage descends slowly the flour will be packed harder than if the car riage descends rapidly.

The lower end of the rod 75 (see Fig. 14) is pivotally connected to the bell crank 120 having arms 121 and 122 provided with anti-friction rollers 123, said bell cranks being loosely mounted on the shaft 106 in the path of a dog 124 adjustably secured on a vertical rod 125. A pivoted lever 126 has a forked end pivotally connected with the pinion 115 and an arm 127 .con nected by a rod 128 with a lever 129 (see Figs. 1 and 13). This lever is loosely mounted on the shaft 138 and provided with a forked arm 128 arranged to engage a collar 128 adjustably secured on the rod 128. The lever 129 has-upwardly-turned ends 129 that extend above the level and between the bars 104 and conveyer chains 137 that pass around sprockets 137 secured on the shaft 138. When the carriage 100 descends the bars 104 will pass down between the conveyer chains which engage the bottom of the sack and remove it from the platform If desired the collar I28 (an be moved out of the path of the forked arm 12! and the operator can oscillate the lever 126 by tlumnnipnhtion of the rod 128.

The lever 126 is pluvibd on one side with a cam surfaceil 30 in the path of a lug 131 on the-rack bar 119.

' when this rack has reached a certain point in the ascent the lower end of said rod depends between stops 134 in i the path of a lug 135 on the lever 126 and acts asa stop toprevcnt the oscillation of the lever and the ascent of the carriage until the yoke 47 has been tilted by the balancing of the scale hopper. I

The'following is a brief description of the operation of the machine: Assuming that one of the scale hoppers is filled with flour and'the other empty, theattendant will place a sack on the cylindrical lower end of the spout inclosing the packing auger and oscillate the lever 126 to start the carriage. When the dog 124 engages the arm 122 the rod 75 will be drawn downward, the filled hopper will be opened and its contents delivered to the packing auger beneath. The bottom of the other scale hopper will be simultaneously closed. This operation takes place after the dog 124 actuates the arm 122 and before it engages the arm 121. When the dog 1'24 engages the arm 121 the rod 75, having previously been returned to its normal position by the spring-79, will be raised and the plate 72 engaging the vertically movable shaft above it, that is in its depressed position, will raise the said shaft and the lever carried thereby, releasing the cut-off mechanism and opening the bottom of the measure to allow its contents to be discharged into the scale hopper beneath. The capacity of the'measure will be regulated according to the size of thesack to be filled and nearly'enough flour or other :material to balance the jscale will be discharged into the hopper immediately uponopening the bottom of the measure. An additional quantity will be delivered to the scale hopper through the operation of the drip feed device. The cut-off device will make a quarter-turn and engaging the stop lever in its raised position will be held 'againstfurther movementnntil the lever and its shaft are depressed As soon as the scale balances the beam 57 will be tilted and engaging the pawl or bell-cran" that holds the shaft in its raised position will trip the same and allow the shaft to return to its normal position. The cut-off will again be released to make another quarter-turn to the starting point and close the discharge opening in the bottom of the'measure. By this time the sack carriage will have been depressed to its lowest position, filled sack automatically removed and during such removal the lever 129 will be operated to again set thecarriage in motion and repeat the operation .1
